L62GB BASO® Safety Shutoff Device
Installation
IMPORTANT: Only qualified personnel should
install or service BASO® Gas Products. These
instructions are a guide for such personnel. Carefully
follow all instructions in this document and all
instructions for the appliance.
!
WARNING: Risk of Explosion or Fire.
Shut off the gas supply at the main manual shutoff
valve before installing or servicing the L62GB.
Failure to shut of the gas supply can result in the
release of gas during installation or servicing, which
can lead to an explosion or fire, and may result in
severe personal injury or death.
!
CAUTION: Risk of Electric Shock.
Disconnect power supply before making electrical
connections to avoid electric shock.
IMPORTANT: Make all gas installations in
accordance with applicable local, national, and
regional regulations.
To install the L62GB.
1. Turn off power to the appliance.
2. Turn off gas at the main manual shutoff valve
adjacent to the appliance.
3. Remove the L62GB cover by loosening the screw
on the front of the device.
IMPORTANT: Do not loosen or tighten the
brass hex nut that fastens the brass terminal
bushing to the plastic switch housing. The machined
flats on the terminal bushing must be parallel to the
flats on the switch housing. If not, the switch power
unit may distort and cause the safety switch to fail.
4. Mount the L62GB in any convenient position using
the mounting holes in the back of the case.
5. Push the circuit wires through the conduit opening
on the side of the device, strip the ends of the
wires just enough to put the bare wire under the
terminal screws, and attach them to the two wire
terminals.
!
WARNING: Risk of Explosion or Fire.
Do not attach both wires to one terminal on the
L62GB. Doing so bypasses and eliminates all safety
features provided by the L62GB, can lead to an
explosion or fire, and may result in severe personal
injury or death.
!
WARNING: Risk of Explosion or Fire.
Verify that this device is wired in series electrically
with thermostats and other appliance operating
controls. Wiring the device in parallel with such
controls will defeat the safety features of this device
and may result in severe personal injury or death.
6. Replace the cover. Do not loosen or tighten the
brass hex nut.
7. Connect the pilot burner orifice fitting to the pilot
outlet on the L62GB with 1/4 in. outside diameter
tubing, and connect the pilot gas inlet with the gas
manifold upstream from the automatic valve.
Note: The pilot line connection is bidirectional as
indicated by the arrows pointing in either direction.
This provides the option of connecting the pilot gas
inlet and outlet in either position.
8. Attach the thermocouple securely to the pilot
burner, and screw the terminal end to the BASO®
power unit terminal on the L62GB. Make sure that
this connection is clean. Tighten the thermocouple
lead nut finger tight plus a maximum of 1/8 turn.
Do not overtighten.
